\VATER-HE ATER.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed July 17, 1907. a Serial No. 384,185.

To all whom it may concern:

Be it known that I, LEWIS C. LEWIS, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in ater-Heaters, of which the following is a specification.

My invention relates to water heaters and has for its object the provision of a device of this character constructed in such manner that cold water under pressure may be supplied continuously to the heater and will be heated to a high degree during its passage through the heater, whereby a continuous supply of hot water may be had at all times.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

In the accompanying drawing: Figure l is a vertical section of a water heater constructed in accordance with the invention, Fig. 2 is a horizontal section upon line wm of Fig. 1, Fig. 3 is a plan View illustrating an arrangement of tubes hereinafter clescribed, with the cap plate removed, and Fig. 1 is an enlarged sectional view through the upper portion of two of the water conducting tubes and through a portion of said cap plate.

Like numerals designate corresponding parts in all of the figures of the drawing.

Referring to the drawing, the numeral 5 designates a supporting spider which is mounted upon legs 6. One of these legs is hollow and a gas supply pipe 7 conducts gas to the interior of said hollow leg, the said gas passing from said hollow leg to the interior of an annular hollow ring 8 which is supported by the spider. This spider also supports an outer inclosing casing 9 which is provided with a lining of asbestos or other heat resisting material indicated at 10.

A plurality of tubes indicated in a general way at 11, are vertically disposed between a base plate 12 and a cap plate 13. An annular ring 14: surrounds the outer row of tubes; an annular ring 15 spaces the outer row of tubes from the inner row of tubes and an annular ring 16 lies within the inner row of tubes. These rings are connected by a bottom plate 17 and the cap plate 13 is pro vided with flanges 18 and 19, which fit down over the rings 14 and 16, the ring 15 having openings 20 formed therein for the reception 0 ordinary bolts 21, said bolts being adapted to bolt the cap plate 13 down upon the ring and to clamp a gasket indicated at 22 between the lower face of said cap plate and the upper face of the rings. The construction of the base plate is substantially the same as the construction of the cap plate, said base plate surrounding rings 23, 2% and 25 which correspond to the rings 14:, 15 and 16.

A number of gas burners indicated at 26, are arranged around the vertically disposed tubes 11, the inner faces of said burners being inclined as at 27 to direct the gas at an angle across the tubes 11. These burners are provided with depending portions 28 into which gas is directed through nozzles 29, said nozzles in turn communicating with the ring 8. Air is drawn in at 30 around the nozzles, the burners being supported by spiders indicated at 31, said spiders supporting the burners from the nozzles.

The operation of the device is as follows: lVater is supplied to the heater through an inlet pipe indicated at 32. Water passes from this pipe to one of the vertically d1S posed pipes 33 to the upper end of sald pipe, where it enters between the rings 14: and 16. This tube 33 at its upper end is in communication with one of the vertically disposed tubes 3 1 of the inner row of tubes and the water descends through this tube to the lower portion of the heater. It will be noted that artit-ions (see Figs. 2 and are so disposed as to direct the water in the path hereinafter described. At its lower end the tube 34 is in communication with another inner tube 35 and it ascends through this tube which is at its upper end in communication with another inner tube 36. The water descends through this inner tube 36, which it will be noted, is in communication at the lower end thereof withan inner tube 37. This tube 37 is in communication at its upper end with an inner tube 38, the water descending through this inner tube 38 and passing at the base plate over to the tube 39. The water ascends through the tube 39 and passes over at the upper end of the tube to an inner tube -10 descending through said tube and passing over into a tube 41. It ascends through this tube and passes over at the upper end thereof into the tube 42. This operation is continued until the ,water passes all around the inner row of tubes, descending finally through an inner tube 43 which is in communication at its lower end with one of the outer tubes 44. The water ascends through this tube 4A and at its upper end passes over and descends through an outer tube 45. At the lower end of this tube, the water passes over into and ascends through an outer tube &6. At the upper end of this tube, the water passes over into and descends through the outer tube &7. This operation continues around the row of outer tubes, the water alternately ascending and descending until the tube 48 is reached, the water ascending through this tube and being drawn off through a discharge pipe 49. By virtue of the construction herein shown and described, the water is not only caused to travel in a devious path, being constantly subjected to the action of heat from the burners 26 during its passage, but this is accomplished without the use of coils, only straight tubes being used in the construction of the heater. This is a particularly advantageous construction by reason of the fact that sediment soon collects in heaters of this character, rendering it necessary to clean the tubes and with spiral or circular coils, it is almost impossible to do this. With the structure herein shown and described, it is but necessary to remove the bolts that hold the cap and base plate in position in order to remove the tubes from the heater, together with the rings to which they are secured, when it is desired to clean them.

From the foregoing description, it will be seen that simple and efficient means. are

herein provided for accomplishing the objects of the invention, but while the ele-.,

ments shown and described are well adapted to serve the purpose for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

What I claim is:

1. In a device of the character described,

the combination with an inner row of tubes, of an outer row of tubes, means for heating said tubes, means for conducting water to said tubes, means for conducting water'from said tubes, the water passing alternately up and down entirely through one row of tubes and then passing alternately up and down entirely through the other row of tubes, and a casing inclosing all of said tubes.

2. In a device of the character described, the combination with an inner row of vertically disposed tubes, of an outer row of vertically disposed tubes, said outer row of tubes inclosing said inner row of tubes, means for heating said tubes, means for conducting water to said tubes, and means for conducting water from said tubes, the Water passing alternately up and down entirely through the inner row of tubes, and then passing alternately up and down entirely through said outer row of tubes.

3. In a device of the character described, the combination with an inner row of vertically disposed tubes, of an outer row of vertically disposed tubes, said outer row of tubes, inclosing said inner row of tubes, means for heating said tubes, means for conducting water to said tubes, means for conducting water from said tubes, the Water passing alternately up and down entirely through the inner row of tubes, and then passing alternately up and down entirely through said outer row of tubes, and an inclosing casing for all of said tubes.

4. In a water heater, the combination with a row of tubes, of means for conducting water to said tubes, means for conducting water from said tubes, a member divided into a plurality of compartments which is located at the upper end of the tube, and a member divided into a plurality of compartments located at the lower end of the .tnhes,,,two of said tubes communicating with each of the compartments ofthe upper member, and two of said tubes communicating with each of the compartments of the lower member, but both of the tubes that communicate wit-h any given compartment of the upper member communicating with separate compartments of-.the lower member.

In testimony whereof I affix my signature aincpresence of two witnesses.
